3.2-7 A pan is placed above a camp fire flame. The pan can be modeled as a circular disk with thickness th = 0.25 inch and diameter D = 8 inch. The pan is made of material with density ρ = 7870 kg/m 3 , specific heat capacity c = 450 J/kg-K, and conductivity k = 70 W/m-K. The bottom side of the plate is exposed to radiation from the flame at T flame = 650°C. The upper side of the pan is exposed to radiation with the environment at T = 15°C. The emissivity of the pan surface is ε = 0.8. The upper side of the pan is also exposed to convection with the environment. The heat transfer coefficient depends on the surface temperature of the pan (
